COOLING DEVICE Filed July 10, 1926 2 Sheets-Sheet 2 [HUGH K; MUM a E Z 52 Patented Nov. 17, 1931 PATENT OFFICE HARRY H. SOHUTZ, F HOUSTON,TEXAS- COOLING" DEVICE Application filed July 10,

This invent-ion relates to new and useful improvements in a coolingdevice.

7 One object of the invention is to provide a cooling device of thecharacter described,

specially designed for use in buildings, and rooms for the purpose ofmaintaining a low temperature therein.

Another object of the invention is to pro- 'vide a device of thecharacter described em- 1 bodying the use of an evaporation coil andmeans for inducing the circulation of a refrigerant therethrough by theevaporation of which, in'said coil, the atmosphere surrounding said coilwill be cooled.

A further feature of the invention resides in the provision of aportable device, of convenient construction and arrangement wherebyammonia or some other suitable refrigerant may be utilized through theinstrumentality of coils to lower the temperature of the surroundingatmosphere.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an exam le of which is given in this specificationan illustrated in the accompanying drawings wherein Figure 1 shows avertical sectional view of the device.

Figure 2 shows a cross sectional view, taken on the line 2-2 of Figure1.

Figure 3 shows a front elevation of the device, and

Figure 4 shows the side view of a modified form of the device.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures the numeral1 desl nates a suitable housing, preferably mounted on casters sothat itwill be portable and located outside of the room to be cooled. Thehousing may be in the form of an open-work cage-like structure, asillustrated in Figures 1 and 3. The numeral 2 designates aconcavo-convex deflector which is connected to the upper end of atubular support 3. The upper end of the support 8 carries a ball 3 andthe deflector has a socket member 2' which receives this ball 1926.Serial No. 121,666.

and forms therewith a ball and socket joint. This sugport may beconnected to the top of the ousing 1, if desired, as shown in Figures 1and 3, or it may be mounted on a separate pedestal 4, if desired, asshown in Figure 4. This deflector 2 is intended to deflect the cold airin any desired direction. Within the housing 1 there is an electricmotor 5 which is operatively connected, in the conventional mannershown, with the conventional type of compressor 6. There is also a tank7 within the housing 1 provided as a receiver for a suitable liquidrefrigerant such as ammonia. An outlet pipe 8 leads from the compressor6 and leading into the compressor there is a delivery line 9 which leadsthrough the tubular support 3 and is formed into a helical evaporationcoil 10 within the deflector 2 and is connected with a flow line 11which is located in said 70 support 3 and is connected into the topportion of the tank 7. The pipe 8 is formed into a spiralled condensercoil 12 which in turn is connected into the top of the tank 7 throughthe pipe 13. A suitable expansion valve 16 is incorporated into the line11.

The gaseous refrigerant is withdrawn from the coil 10 through the line 9by the compressor 6 and is then delivered through pipe 8 to thecondenser coil 12 where it is liquefied. From the condenser coil 12 theliquefied gas flows to the receiver tank 7, through pipe 13 and passesthence through the line 11, to the evaporation coil 10 in which itevaporates assuming the form of gas. The temperature of the coil 10 andthe surrounding atmosphere will be thereby lowered.

Mounted within the deflector 2 there is the blow fan 15 mounted behindthe coil 10 in the deflector and adapted to blow the cool air out intothe room.

What I claim is A combination with a housing, ofa support, aconcave-convex deflector having an adjustable universal connection withthe upper end of said support and provided with an opening, a compressorin the housing, an electric motor having a driving connection with thecompressor, a refrigerant tank within the housing, a liquid supply pipeleading from said tank to a helical evaporator co in said deflector, agas suction pipe leading from the evaporator to the comssor, a spiralledcondenser coil connected tween the compressor and the refrigerant tankand an air current generator within the deflector behind the evaporatorcoil so that air will be drawn through said ofening and forced throughthe eva rator co In testimony whereof have signed my name to thisspecification.
